I have a .50 CVA, my first BP gun given to me as a kit. I too had problems with accuracy shooting round balls with pillow tick patches and home made jube (read Crisco). I read an article in Musselblasts magazine from NMLRA that said the issue was burnt patches. Sure enough, I picked up some from down range and they were smoldering and had holes burnt in them. It was suggested in the article that loading the powder followed by about a half charge of Cream of Wheat cereal then the patched ball would help. What the heck, got some CoW and tried it. Before shooting breakfast down range I could only hit the side of a barn if'n I was in the barn. After the cereal load I got 2" to 3" groups at 50 yards. Cheap enough to try and if it don't work you have some breakfast.
